Animation window does not update when the GameObject with the Animation is deleted until the mouse cursor enters the Animation window

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Create a new Cube GameObject (GameObject > 3D Object > Cube)
3. Open the Animation window (Window > Animation > Animation)
4. Dock the Animation window 
5. Create a new Animation
6. Delete the Cube GameObject
7. Observe the Animation window

Actual results: The Animation window still shows the Cube's Animation

Expected results: The Animation disappears from the Animation window and "No animatable object selected." text is shown

Reproducible with versions: 2022.3.66f1, 6000.0.58f1, 6000.1.16f1, 6000.2.4f1

Not reproducible with versions: 6000.3.0a1, 6000.3.0b1

Tested on (OS): macOS Silicon Sequoia 15.6.1

Notes:

• 6000.3 seems to be unaffected by this issue
• The Animation window updates when mouse cursor is hovered over it after reproduction
